Rick Santorum cancelled his Suday morning Florida appearances after his 3-year-old daughter Bella fell ill on Saturday. It’s not clear yet when he will resume campaigning in Florida. He is scheduled to appear in Boca Raton Monday morning.

Hogan Gidley, Santorum’s communications director, released a statement saying: “Rick and his wife Karen are admitting their daughter Bella to Children’s Hospital of Philadelphia this evening. The campaign will cancel Rick’s upcoming Sunday morning Florida campaign schedule. However, Rick intends to return to Florida and resume the campaign schedule as soon as is possible”

Bella suffers from Trisomy 18, a genetic condition caused by the presence of all or part of an extra 18th chromosome. When asked about her, Santorum says his daughter was not expected to survive until her first birthday and often has to catch himself to stop from tears.

“I have a little girl who’s 3 years old,” he told Christian conservatives in Iowa before winning that lead-off contest.

“I don’t know whether her life is going to be measured — it’s always been measured — in days and weeks. Yet here I am. … because I feel like I wouldn’t be a good dad if I wasn’t out here fighting for a country that would see the dignity in her and every other child.”

When voters ask him about her, he calls the decision to campaign “gut-retching” but says he goes forward for all special needs families.

“You think she’s fine, and then one cold and she’s this close to dying,” he told The Washington Post last year in an interview.

In October, he missed one of Bella’s surgeries to participate in a debate and told the audience that he planned to take an all-night flight home from Las Vegas to be with her.

“I look at the simplicity and love she emits,” Santorum said in a web video his campaign released after his scheduling drew questions, “and it’s clear to me we’re the disabled ones.”
